We carry a diversity of Mexican mineral specimens both from purchased
collections and from more modern finds. On the following pages you will
encounter crystals from many locations and in many species. Most are quite
aesthetic and normally very reasonable in price however, high quality, damage
free specimens of unusual or highly aesthetic species from Mexico have always
commanded top dollar. Because we purchase older collections we often have
fine examples of older Mexican minerals that are not common in today's
contemporary mineral market.

Amethyst
from Los Viras Mine, Vera Cruz, Mexico....fantastic, HUGE, clusters both on
and off matrix. Skeletal, sceptered, reverse scepters and all
varieties of oddities! A new discovery of this classic material which
totally outclasses the old material.

OKO-404
Mimetite and Wulfenite Mapimi, Durango, Mexico. Ex. Paul and Dawne Dunning
collection. This specimen is composed of tiny blades of clear wulfenite mixed
amongst the apple green mimetite crystal. All sides of the piece have decent to
very nice crystallization. No damage and mounted in a perky box. $30

OKO-394

OKO-394
Sulfur Baja California, Mexico. Ex. Paul and Dawne Dunning collection.
This is a fine crystal that measures 2 x 1.5 x 1.5 cm. It is translucent
(transparent in some areas), bright yellow, and has the expected waxy luster.
$40

OKP-370

OKP-370 Wulfenite Los Lamentos Mountains,
Chihuahua, Mexico. Ex. Caroline Les collection. These are obviously
the more unusual and uncommon variety of crystals from this location. The
tabs (not blocky opaque crystals) are transparent and up to a cm each on edge.
There is some chipping on the crystals to the right on the piece as seen.
7.5 x 6 x 4 cm in size. $395

OKO-567

Back

OKO-567 Wulfenite and Mimetite San Francisco
Mine, Sonora, Mexico. Ex. Caroline Les collection. This cluster
measures 6 x 6 x 3.1 cm overall and contains large crystals to over 2 cm each on
edge. The crystals are transparent, amber/yellow in color and included and
partially coated by balls of mimetite. Several crystals on back and edge
are cleaved. Front is excellent. $395

OKO-565

Back??

Marix of crystallized quartz

OKO-565 Acanthite with Pyrite on Quartz
San Juan Rayas Mine, Guanajuato, Guanajuato, Mexico. This is a fine
miniature that measures 5.9 x 4 x 3 cm. The nest of interwoven acanthites
sits up high on crystallized quartz. There a few small pyrites but these
are all on the back of the specimen. The best crystals of acanthite are
crude, blocky, and mostly hollow. These seem to be mainly on the left
flank of the nest. Most crystals are smaller making the price reasonable
on what would be an outrageously fine specimen if they were a bit larger.
The back could easily be considered the front by many collectors as the
crystallized matrix is better. No damage. $800

OKO-553

OKO-553 Manganoan Adamite on Arseniosiderite
Mina Ojuela, Mapimi, Durango, Mexico. Ex Harold Dibble collection.
This is an attractive piece of this very rare, very aesthetic material. It
measures 9 x 4.2 x 3 cm with most of the adamites being on the right side, as
seen. The only damage is a broken crystal in front directly on the edge of
the specimen. These are expensive specimens so the price on this one
reflects that damage. It could be trimmed off but there is the risk of
damaging other crystals. The color and luster are actually better than the
images indicate. As is $1,800.

OKM-207

OKM-207 Gypsum Naica Mine, Naica Mun. de Saucillo,
Chihuahua, Mexico. Ex. Harold L. Dibble collection. This beautiful
little cluster measures 9 x 6 x 5 cm and has crystals to 5 cm each. One
side of specimen (front, first image) is very clean and other side (back, second
image) is slightly frosted. Crystals are transparent and have excellent
luster. One small crystal is missing but it looks like and old break so I
do not believe it is damage and it is certainly not obvious or distracting.
This is a very high quality specimen for this material. $125

OKP-355

OKP-355 Wulfenite Chihuahua,
Mexico. Ex. Harold L. Dibble collection. This specimen is a long,
sharp shard that has crystals on both sides with the one photographed being
better. The crystals are transparent with one being zoned (second photo,
poorly done but you will get the idea). Several smaller crystals are broke
but all the big, noticeable ones are nice. 13.7 x 4.5 x 2.5 cm. $45

OKM-215 Calcite Guanajuato,
Mexico. Ex. Harold L. Dibble collection. The poker chip crystals have
always been a popular Mexican classic and they have become more difficult to
find. This grouping measures 11.4 x 6.5 x 4.5 cm. It sits on edge
for display and has only the slightest of rubs to a few crystals. $60

OKP-347 Adamite Mapimi, Durango,
Mexico. Ex. John Davis collection. This this a very fine, small
grouping of prismatic crystals. There is no damage to the piece which
measures 4 x 2.8 x .8 cm in size. The crystals are exceptionally lustrous
and transparent. $40

OKP-325

OKP-325 Wulfenite and Mimetite
Los Lamento Mountains, Chihuahua, Mexico. Ex. Caroline Les collection.
This specimen is a very high luster example of the classic Los Lamentos
material, however the crystals are very small and transparent. The piece
measures 8.5 x 7 x 6 cm overall. There is only one tiny spot with a couple
of missing crystals. I think this damage is impossible to find without
using magnification and it is well to the side. Crystallization on back to
but poorer in quality. All views are nice. Comes with a custom
engraved acrylic base. $600

OKP-345 Wulfenite Erupcion
Mine, Los Lomentos, Chihuahua, Mexico. Ex. Caroline Les collection.
This amazing piece is composed primarily of one very large (over 4 cm!),
butterscotch colored crystal. It is a fine specimen and displays from any
direction. The only damage anywhere on it is a tiny chip on the top corner
of the crystal is visible from the backside. The specimen comes with a
custom engraved acrylic base. A superb miniature! $950

OKP-340

OKP-340 Wulfenite, Mimetite, Cerussite
Erupcion Mine, Los Lomentos, Chihuahua, Mexico. Ex. Caroline Les
collection. This example is one of the most unusual and aesthetic I have
seen from Los Lomentos. The piece shows large (to almost 2 cm each)
tabular clear, yellow wulfenites with a second generation of translucent brown
wulfenites on these. Green mimetite and white/clear cerussite as great
contrast to this plate of crystals. Sorry, I neglected to show the back
which is partially crystallized by fine cerussites and some wulfenite.
Everything is damage-free and aesthetically displayed as most of the larges
wulfenites are on edge. The specimen measures 8.7 x 6 x 2 cm. The
specimen comes with a custom engraved acrylic base. An exceptional
wulfenite specimen an any arena $1,500

OKP-197 Calcite and Pyrite
Chihuahua, Mexico. Ex. John Davis Collection. This miniature is very
aesthetic in-hand. It measures 4 x 3 x 2.3 cm. One calcite on back
is cleaved and a very tiny one on the side also. Even given this, the
specimen displays very well. $40

OKN-809

OKN-809 Galena Naica, Chihuahua,
Mexico. Ex. Harold Dibble collection. This fine plate of
interlocking crystals measures 8.7 x 5.1 x 3 cm. It has a very high luster
and no damage. There is some edge contacting but the edges are generally
in good condition. Minor pyrite and quartz on edges and base.
Mounted on acrylic base. $40

OKP-320

OKP-320 Wulfenite and Mimetite
San Francisco Mine, Sonora, Mexico.
Ex. Caroline Les Collection. This is a fine example of large wulfenite
blades (to more than 2 cm each on edge) that compose a specimen measuring 8.1 x
5 x 3.1 cm. What makes it really interesting is the two generations of
orange mimetite balls on the crystals. The first generation are very small
and fully coat each crystal. The later generation are brighter orange,
larger and on show in partial coverage. The display is very nice and
different from the normally material seen from this location. The piece is
in excellent condition, as seen. The specimen comes with a custom engraved
acrylic base, as seen in the images. $400

OKN-875

OKN-875
Quartz Zactecas, Mexico. Ex. Paul and Dawne Dunning collection. A 5.4 x 3.4
x 3.2 cm piece with several generations of quartz. White to gray to milky color
(each generation is different). There is one quartz on the edge with a tiny tip
ding otherwise excellent condition. $25

OKN-867
Fluorite Chihuahua, Mexico. Ex. Paul and Dawne Dunning collection. A
fine plate of yellow cubes with nice three-dimensional mounds of crystals. 9 x
6.5 x 3.2 cm. Cubes are frosted in appearance. Only damage is to a couple
cubes on high points and it is minimal and not distracting. $35

OKN-865

OKN-865
Fluorite and accessories Naica, Mexico. Ex. Paul and Dawne Dunning
collection. A fine example with one large octahedron (Aztec Pyramid style) 3.7
cm on edge. Other fluorites and accessories mixed on other side of piece.
Damage-free upper display surface with contact on base or back depending on how
you choose to display it. 8.8 x 6.5 x 3.3 cm. $45

OKO-516

OKO-516
Barite Characas, San Luis Potosi, Mexico. Ex. Harold L. Dibble collection.
A plate of white barite crystals that jut out in all directions. The piece
measures 8.4 x 8.1 x 6.4 cm with crystals to 2.5 cm each. Many have steep
terminations that would almost allow them to pass as quartz crystals. One
crystal broke off near edge of piece as seen. $60

OKO-195
Goethite pseudo after Pyrite Mexico. Ex. Dr. Steve Chamberlain collection.
Three examples, all floaters without damage up to 1.4 cm in diameter each. These
are “Iron Cross” twins and nice examples of them. Someone will probably split up
this set and do well selling them. $50

OKO-165 Pyrargyrite Guanajuato, Mexico. Paul and Dawne Dunning
collection. A superb little matrix specimen with no damage, no contacts, high
luster, great form… this has it all. 1.6 x 1.6 x 1 cm overall. The crystal
cluster sits high on the matrix and views great form any direction. $75

OKN-785

OKN-785
Grossular Lake Joco, Mexico. Ex. Harold L. Dibble collection. A large
pair of intergrown crystals, rather large for the location, for sure, that
measure 7.2 x 7.2 x 6.3 cm. A couple of minor contacts, as seen, but overall in
nice condition. Good luster and great for as one would expect from material
from this find. $95

OKN-767

OKN-767
Danburite La Aurora Mine, Characas, San Luis Potosi, Mexico. Ex. Harold L.
Dibble collection. A typical crystal for a popular occurrence. This on
measures 7.2 x 3 x 1.8 cm and is gemmier than most. Good regions for faceting
if desired. The termination has two small chips as seen otherwise the piece is
in good condition. $40

OKO-155

Bottom

OKO-155
Arsenopyrite Chihuahua, Mexico. An impressive floater of competition level
caliber. Not especially uncommon but uncommonly aesthetic and well formed. No
damage and only a tiny bit of glue on base of this wonderful 2 x 1.8 x 1.2 cm
grouping. Great luster, no decay. $60

OKO-725 Calcite Potasi
Mine, Franciso Potillo, Santa Eulalia District, Mun de Aquiles Serdan,
Chihuahua, Mexico. Ex. Harold L. Dibble collection. This one is a
real looker. It measures 13.7 x 11.5 x 8 cm overall with the larger
crystals up to 2.3 cm each. There are three stalactites missing their tops.
That is it for damage, with all other surfaces and crystals being very nice.
A show example with good views all around. $300

OKO-146

OKO-146
Fluorapatite Cerro de Mecado, Durango, Mexico. Ex. Dr. Steve Chamberlain
collection. A pair of transparent to translucent, bright yellow/green crystals
to 1.4 cm ling each. This is a good example of the material with lots of unusual faces
and atypical form. No visible damage, but I have not looked at the bases and
have left them mounted in the perky box. I suspect that each is a floater. $20
